The visitor will visit object ``obj``. The visitor will first determine if there is a registered (via ``@register()``) visit function for the type of object. If there is, it will be called, and ``(visitor, obj, *args, **kwargs)`` will be passed to the user visit function. The visitor will not recurse if there is a user-registered visit function and: * It returns ``False``; or * It returns ``None`` (or doesn't return anything) and ``visitor.defaultStop`` is ``True`` (non-default) Otherwise, the visitor will proceed to dispatch to one of ``self.visitObject()``, ``self.visitList()``, ``self.visitDict()``, or ``self.visitLeaf()`` (any of which can be overriden in a subclass).
